CONDENSER.

Application filed May 29, 1922.' Serial No. 564,293.

To all 107mm t may concern:

Be it known that I, ALBERT E. BERDON, citizen ofthe United States, residing at Detroit, in the county. of lVayne and State of Michigan, have invented a certain new and useful Improvement in Condensers, of which the following is a full, clear, concise, and exact description.

My invention relates to condensers, the condensers of my invention being of particular service when employed in flexible cords that serve to connect radio receiving equipment with lamp sockets, although the invention is not to be limited to any particular use to which it may be put.

The condenser of my invention includes two assembled co-axial conduits, two wire conducto-rs, one passing through the bore o-f each conduit, two condenser plates between said conduits each having one of said wires individual thereto and'connected therewith, and a dielectric between said plates and maintaining them in spaced apart relation.

In the preferred embodiment of my invention tangs are stamped from the condenser plates, these tangs extending away from each other and being received in notches that arc formed in the adjacent faces of the conduits. The adjacent ends of the conduits are desirably flanged and a band preferably surrounds these flanges to seal the space between the same and to clamp the flanges close together` whereby the condenser plates are held in fixed relative positions.

The invention will be more fullyexplained by reference to the accompanying drawing in which Fig. 1 is a longitudinal sectional view showing the preferred embodiment thereof; Fig. 2 is a side elevation on a smaller scale; Fig. 3 is a view on line 3 3 of Fig. 1; Fig. 4 is a perspective view illustrating one condenser plate and its wire in separated relation; Yand Fig. 5 is a perspective view illustrating one of the flanged conduits.

Like parts are indicated by similar characters of reference throughout the different figures.

The conduits 1 and 2 are tubelike and are arranged to be co-axial. The adjacent ends of the conduits are formed with flanges 3 and 4. The condenser includes two circular metallic plates 5 and 6 that are separated by a solid dielectric 7 of mica or other suitable material. A band 8 surrounds the flanges `and has its edge portions inwardly bent into clamping engagement with the flanges as indicated at 9. The edges of the flanges are desirably chamferred to conform to the bends of the band. By the as sembly thus edected, the condenser plates,

' the dielectric therebetween, and the conduits are firmly clamped in assembly.

To further guard against the shiftingof the condenser plates and to afford a con# venient means of attaching their wires 10 and 11 thereto, said condenser plates are formed with tangs 12 and 13 stamped thereon and which are respectively received in notches 14 and 15 formed in the adjacent faces of the conduits. The lateral walls of the notches engage the tangs and prevent the shifting of the condenser plates that have such tangs.

The bores of the conduits are desirably sufficiently large to contain the wires with the serving thereon. The inner ends of the wires are bared and pass through openings 16 formed in the tangs, lumps of solder 17 applied to the inner ends of the wires serving to maintain them in firm mechanical and electrical connection with the tangs.

The entire condenser structure is rendered water proof and moisture proof by the band 8 at the space between the adjacent faces of the conduit flanges and by the serving around the wires that fills the bores of the conduits. I have not deemed it necessary to illustrate the plug by which the flexible wires 10 and 11 are brought into electrical connection with the lamp socket, nor the terminal plug or tag by which the wires are connected with the receiving instrument.

lhile I have herein lshown and particular-ly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention, but having thus described my invention I claim as new and desire to secure by Letters Patent the following 1. A condenser including two co-axial flanged conduits with the flanges thereof slightly spaced apart; two wire conductors, one passing through the bore of each conduit; twov condenser plates between said flanges each having one of said wires individual thereto and having a tang thereon with which such wire is connected, the tangs extending away from each other and being received in notches that .ane formed in the adjacent faces of said'conduits; a solid dielectric between said plates and maintaining them in spaced apart relation; and a band surrounding said flanges and having its edge portions bent into clamping engagement therewith whereby the condenser plates are held in fixed relative positions.

2. A condenser including two co-axial conduits; two wire conductors, one passing through the bore of each conduit; two condenser plates between ksaid conduits each havingpone of said wires individual thereto and having a tang thereon with which such wire is connected, the tangs extending away from each other and being received in notches 'that are formed in the adjacent faces of said conduits; a solid dielectric between said plates and maintaining them in spaced apart relation; and a band surrounding said conduits and having its edge portions bent into clamping engagement therewith whereby the condenser plates are held in lixed rel-i ativel positions.

3. A condenser including two assembled co-axial flanged conduits with the lianges thereof slightly spaced apart; two wire conductors, one passing through the bore of each conduit; two condenser platesbetween said langes each having one of said wires individual thereto and having ay tang thereon with which such wire is connected, the tangs extending away from each other and being received in notches that are Jformed in the adjacent faces of said conduits; and a solid dielectric between said plates and maintaining them in spaced apart relations.

4. A condenser including two assembled co-axial Vconduits; tw o wire conductors7 one passing throughthe bore of each conduit; two condenser plates-between said conduits each having one of said wires individual thereto and having a tang thereon with which such wire is connected, thetangs extending away rom each other and ybeing received in notches that are formed in the adjacent y dielectric between said plates and maintaining them in spaced apart relation.

In witness whereof, I hereunto subscribe my name. this 22nd day of May A. D., 1922.
